How to change transmission oil a on '95 BMW 740iL

When I start my 740 in the morning and take it out, during the first 2 minutes or so the gears take long to shift. I would be driving 25 mph and the rpm would be still at almost 3 and wouldn't shift. It takes a while for it to come back to normal. What do you think this is from? I had a mechanic change the transmission oil for $200 and I am not sure if he did it right or if he put the right amount of oil in there. And the problem still occurs.
I want to change the transmission oil the right way, so I want to do it over.

Also, how can I get a BMW technical information system (TIS) CD?

Pop along to Ebay and buy the TIS there.

You will find most marques for sale.

Re the oil, it is a case of undoing the drain plug, draining and filling through the fill plug. A Haynes manual will tell you where these are and the type/capacity of the transmission.

The oil change in itself is unlikely to create the problem. Check the level (procedure in the manual). If the level is low, that might be the problem. Also, if the mech used the wrong type of oil, odd things can happen.

Does this problem rectify itself fully? Modern automatic transmission sometimes have electronically controlled shift valves and the problem may be outside the gearbox itself.

Sounds like you need a new release bearing,while its apart you can ask them to resurface your flywheel and clutch.

You have 2 types of oil: motor oil (molasses color) and transmission oil (translucent pinky-red). Check the levels of both with their respective dipsticks (the transmission oil dipstick is much shorter and found in the belly of the beast). My initial reaction to your symptoms is that it is transmission related. The transmission oil wouldn't create this alone. In fact, it sounds like you're developing an internal hydraulic transmission problem. More specifically, I would point my finger at your torque converter:

Mechanically speaking it is:
motor oil
transmission FLUID, so there is no confusion the two.

You have a dip stick for the oil and the tranny fliud. Check your tranny fluid level according to the manual which should say to get the engine warm, put it in neutral and check it in neutral.
If it is low, add some. If not low, then you can speculate about other possible transmission problems.

Since a transmission should not use alot of fluid, I've never changed mine in 43 years of driving and over a dozen cars, never. I think I paid to have it done once. The transmission filter and gasket are the reasons I do not attempt it myself.
Ride by an Autozone or Advanced Auto Parts and they will gladly check your FLUID level.
Report back if you level was normal and you still have the shifting problems. Or your level was low and after adding the needed amount of fluid you still have issues.

Ehm, well in countries that don't use english, the two fluids are both called "oil" in many cases. Normally, it's not a cause for problems, the 2 oils are fairly different in viscosity and colour (and markings on the bottles...).

Depending on how you drive and other factors (environmental heat, dust etc) you may actually benefit from changing the transmission oil and all pertinent filters once in a while.

sorry, I assumed the op was in the USA. I do not know mechanical teminology in other places except liters for gasoline, and other metric terms.

I am located where both English and French are spoken. Either way, it is known as transmission "oil" - not "fluid"

Changing your transmission oil on a regular basis of 30,000 miles is the usual recommended schedule. When you do this, make sure to change your transmission oil filter as well. Transmission oil gets dirty just the same as engine oil, and needs changing. As your transmission ages, miscellaneous items such as dust, dirt, metal pieces and grime gathers in your transmission oil filter. If not changed, it will infect the clean transmission oil.

You can check your transmission oil to see if it needs changing. Lift the appropriate dipstick to see what shade of pink it is. If it is a nice, bright pinky red, it is clean - no need for changing. If it's reddy-brown, it is ready for changing. Take your car to a transmission repair shop to have this done, and as Rid noted, changing the filter may be beneficial as well.

As a former owner of this model, its the electronics most likely.  Some sensor is not responding correctly at cold temperatures so the transmission shift programming is not meshing with actual driving conditions.

If you live in a cold place, then an oil heater will fix it.

Your problem may be a deeper rooted issue than changing the transmission fluid can fix.
I suggest taking the car to a local BMW specialist. It can be pricey, but if you can find a reasonable shop they might even diagnose it for free
good luck
